The content/file distinction is clear, and validate_smalltalk_method_body is genuinely distinct, but lint vs validate pairs are highly similar in purpose and may cause an agent to select the wrong one without deeper semantics. Descriptions help only slightly because they don't define the exact boundary between linting and validating.

All tool names follow a consistent snake_case verb_noun pattern with an optional _from_file suffix. The naming is predictable across content-string and file-based variants, and validate_smalltalk_method_body fits the same style despite targeting a different input type.

Five tools is a well-scoped number for a focused Smalltalk source validator, covering both linting and validating across content strings and files, plus method body validation. No tool feels unnecessary, and the set is compact rather than bloated.

The core validation and linting workflows are covered for Tonel source code from both content strings and files, along with direct method-body validation. Minor gaps exist in the absence of batch processing, formatting, or a way to validate method bodies from files, but these are workable rather than blocking.
